Description

Technical Field

[0001] This invention belongs to the field of autonomous POS technology, specifically an integrated POS machine for elderly people and meals. Background Technology

[0002] In recent years, a large number of self-service restaurants have emerged, especially in institutions with a large number of diners such as schools and hospitals, where self-service dining has become increasingly popular. Self-service equipment, as the main equipment in self-service restaurants, is used to place cooked dishes for customers to take.

[0003] A patent with publication number CN215416840U discloses a self-service dining device without a cashier, including a weighing base, a support rod, a top cover, and a protective plate. The lower part of the support rod is fixedly mounted on the weighing base, and its upper part is fixedly connected to the top cover located above the weighing base. The protective plate is located on the front surface of the top cover to block saliva. A display screen and a camera are installed on the front surface of the top cover. The display screen is used to indicate food information, price calculation, and personnel information, and the camera is used to identify customer identity information. A control mainboard is also included, located inside the top cover. A weighing sensor is installed at the bottom end of the weighing base. The display screen, camera, and weighing sensor are all electrically connected to the control mainboard. This invention uses upper and lower cameras to identify customers, adapting to people of different heights with high accuracy. The height of the display screen is reasonably designed, and the protective plate on the top cover facilitates customers' access to food while blocking saliva, improving the hygiene and safety of the food.

[0004] Currently, most elderly people purchase and pay for meals using existing automated checkout devices. However, the height and angle of the display screens on these devices are limited. Due to differences in age and gender, elderly people vary greatly in terms of hunchback and body shape. In particular, for some elderly women, the display screens on the checkout counters are too high, making it difficult for them to effectively observe the surface of the screen.

[0005] Therefore, the present invention provides an integrated cash register for elderly meal assistance. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an integrated cash register for elderly meal assistance, comprising an integrated cash register and a fixed support plate fixedly installed on the outer surface of the top of the integrated cash register, and a cash register detachably installed on the inner wall of the fixed support plate. Two sets of infrared detectors are symmetrically fixedly installed on the outer surface of the fixed support plate, and a second motor is fixedly installed on the outer surface of the fixed support plate. A rotating disk is fixedly connected to the output end of the second motor.

[0008] Preferably, multiple sets of hydraulic rods are fixedly installed on both sides of the integrated cash register, and a tightening shell is fixedly connected to the output end of the hydraulic rod. A motor is fixedly installed on both sides of the tightening shell.

[0009] Preferably, a transmission rod is fixedly connected to the output end of the motor, an auxiliary support rod is movably sleeved on the inner wall of the integrated cash register, and a conveyor belt is movably sleeved on the outer surfaces of the transmission rod and the auxiliary support rod.

[0010] Preferably, a waste oil vegetable leaf collection box is provided on one side edge of the tightening shell, and an oil removal tank is provided on the inner wall of the waste oil vegetable leaf collection box. A small water pump is fixedly installed on the inner wall of the oil removal tank.

[0011] Preferably, the top surface of the waste oil vegetable leaf collection box is provided with a scraper strip, and the top surface of the scraper strip is movably connected to the bottom surface of the conveyor belt.

[0012] Preferably, a water spray head is fixedly connected to the output end of the small water pump, and the top surface of the water spray head is located at the bottom edge of the conveyor belt.

[0013] Preferably, a food inspector is fixedly installed on the top surface of the integrated cash register, and protective covers are symmetrically fixedly connected to the two side surfaces of the integrated cash register. The outer surfaces of the two sets of fixed support plates are fixedly connected to the two side surfaces of the food inspector.

[0014] Preferably, a weighing device is fixedly installed on the top surface of the integrated cash register, and an overlapping support plate is fixedly connected to the output end of the weighing device. The outer surface of the overlapping support plate is movably sleeved on the inner wall of the conveyor belt.

[0015] Preferably, an arc-shaped overlapping strip is fixedly installed on the outer surface of the rotating disk at both ends, and a mating buckle is provided on the inner wall of the arc-shaped overlapping strip.

[0016] Preferably, a protective cover is provided on the outer surface of the docking buckle, and the outer surface of the cash register is provided on the inner wall of the protective cover.

[0017] The beneficial effects of this invention are as follows: 1. The integrated cash register for elderly meal assistance described in this invention, when the dishes are moved for billing, uses an infrared detector on the outer surface of the fixed support plate to perform infrared scanning on the elderly person in front of the integrated cash register to detect and process the height of the elderly person. At this time, the infrared detector controls the second motor to rotate the rotating plate, and changes the angle of the cash register on the outer surface of the rotating plate toward the elderly person's head position, so that the screen is kept horizontal with the eyes, avoiding the direct light reflected from the screen into the eyes, which would cause glare and blur the eyes of the elderly person. It achieves the effect of making the screen parallel to the eyes of the elderly person according to different heights, reducing the blurring of the eyes caused by the reflection of the surrounding image. 2. The integrated cash register for elderly care and meal assistance described in this invention, when the conveyor belt is continuously rotated by motor one, a small water pump draws water from the inside of the degreasing tank, and the water mixed with grease-removing detergent directly impacts the outer surface of the conveyor belt. The grease-removing detergent washes the grease on the surface of the conveyor belt. As the conveyor belt continues to slide, the scraper on the top surface of the degreasing tank scrapes off the grease-removing detergent and grease. The inclined surface of the scraper allows the grease-removing detergent to flow into the interior of the degreasing tank, thereby recovering the grease and grease-removing detergent. This achieves the effect of using grease-removing detergent to wash away the grease on the surface and maintain the cleanliness of the surface. 3. The integrated cash register for elderly meal assistance described in this invention allows elderly people to place their trays directly in the middle of the conveyor belt when they choose to weigh their meals. A hydraulic rod retracts the tightening shell, slackening the previously taut conveyor belt. The conveyor belt then falls and overlaps the top surface of the support plate under the weight of the tray. A weighing device then weighs the weight on the top surface of the support plate, and the weight is counted based on the types and weights of the dishes observed in the tray through the food inspector. This achieves the effect of marking the price and weight of the current dishes through the cash register. 4. The integrated cash register for elderly meal assistance described in this invention allows elderly people to choose their own meals by simply placing the selected dishes on the top surface of the conveyor belt. At this time, a pair of transmission rods driven by a motor rotate, causing the conveyor belt to carry the meal tray. When the meal tray moves to the bottom edge of the food inspector, the food inspector counts the types of dishes inside the tray, thereby achieving the effect of individually counting, weighing, and setting prices for the dishes.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 2 and Figure 6 As shown in the figure, an integrated cash register for elderly meal assistance according to an embodiment of the present invention includes an integrated cash register 11 and a fixed support plate 12 fixedly installed on the outer surface of the top of the integrated cash register 11. A cash register 13 is detachably installed on the inner wall of the fixed support plate 12. Two sets of infrared detectors 126 are symmetrically fixedly installed on the outer surface of the fixed support plate 12. A second motor 121 is fixedly installed on the outer surface of the fixed support plate 12. A rotating disk 122 is fixedly connected to the output end of the second motor 121. An arc-shaped overlapping strip 123 is fixedly installed on the outer surface of the rotating disk 122 at both ends. A docking buckle 124 is provided on the inner wall of the arc-shaped overlapping strip 123. A protective cover 125 is provided on the outer surface of the docking buckle 124. The outer surface of the cash register 13 is provided on the inner wall of the protective cover 125.

[0023] When the dishes are moved for billing, the infrared detector 126 on the outer surface of the fixed support plate 12 performs an infrared scan on the elderly person in front of the integrated cash register 11 to detect and process the height of the elderly person. At this time, the infrared detector 126 controls the motor 121 to rotate the rotating plate 122, and changes the angle of the cash register 13 on the outer surface of the rotating plate 122 toward the elderly person's head position, so that the screen is kept horizontal with the eyes, avoiding the screen's reflected light from directly shining into the eyes, which would cause glare and blur the elderly person's vision. This achieves the effect of making the screen parallel to the elderly person's eyes according to different heights, reducing the blurring of the eyes caused by the reflection of the surrounding image.

[0024] like Figures 1 to 4 and Figure 6 - Figure 7 As shown, multiple sets of hydraulic rods a1 are fixedly installed on both sides of the integrated cash register 11. A tightening shell a2 is fixedly connected to the output end of the hydraulic rod a1. A motor a3 is fixedly installed on both sides of the tightening shell a2. A transmission rod a4 is fixedly connected to the output end of the motor a3. An auxiliary support rod a5 is movably sleeved on the inner wall of the integrated cash register 11. A conveyor belt a6 is movably sleeved on the outer surfaces of the transmission rod a4 and the auxiliary support rod a5. A food inspector 111 is fixedly installed on the top surface of the integrated cash register 11. Protective shells 115 are symmetrically fixedly connected to both sides of the integrated cash register 11. The outer surfaces of two sets of fixed support plates 12 are fixedly connected to the two sides of the food inspector 111. A weighing device 113 is fixedly installed on the top surface of the integrated cash register 11. An overlapping support plate 114 is fixedly connected to the output end of the weighing device 113. The outer surface of the overlapping support plate 114 is movably sleeved on the inner wall of the conveyor belt a6.

[0025] When elderly people place trays containing different dishes onto the top surface of conveyor belt a6, they can choose between self-selection and weighing. If they choose self-selection, they simply place the chosen dishes on the top surface of conveyor belt a6. At this time, motor a3 rotates transmission rod a4, causing conveyor belt a6 to move the tray. When the tray reaches the bottom edge of food inspector 111, the inspector counts the types of dishes inside. If the elderly person chooses weighing, they simply place the tray on the conveyor belt. The tray is placed in the middle of the conveyor belt a6. With the help of the hydraulic rod a1, the tightening shell a2 is retracted, and the conveyor belt a6, which was in a taut state, is relaxed. At this time, the conveyor belt a6 will fall and overlap the top surface of the overlapping support plate 114 under the weight of the tray itself. The weight of the top surface of the overlapping support plate 114 is then weighed by the weighing device 113. The weight is also counted based on the type and weight of the dishes inside the tray observed by the food inspector 111. This achieves the effect of marking the price and weight of the current dishes through the cash register 13.

[0026] like Figure 5 As shown, a waste oil vegetable leaf collection box 112 is provided on one edge of the tightening shell a2. An oil removal tank c1 is provided on the inner wall of the waste oil vegetable leaf collection box 112. A small water pump c2 is fixedly installed on the inner wall of the oil removal tank c1. A scraper and diversion strip c4 is provided on the top surface of the waste oil vegetable leaf collection box 112. The top surface of the scraper and diversion strip c4 is movably connected to the bottom surface of the conveyor belt a6. A water spray head c3 is fixedly connected to the output end of the small water pump c2. The top surface of the water spray head c3 is located at the bottom edge of the conveyor belt a6.

[0027] As the conveyor belt a6 rotates continuously under the motor a3, a small water pump c2 draws water from the oil removal tank c1, causing the water mixed with grease and detergent to directly impact the outer surface of the conveyor belt a6. The grease and detergent washes away the grease on the surface of the conveyor belt a6. As the conveyor belt a6 continues to slide, the scraper bar c4 on the top surface of the oil removal tank c1 scrapes off the grease and detergent and grease from the surface of c6. The inclined surface of the scraper bar c4 allows the grease and detergent to flow into the interior of the oil removal tank c1, thereby recovering the grease and detergent. This achieves the effect of using the grease and detergent to wash away the grease on the surface of c6 and to maintain the cleanliness of the c6 surface.

[0028] Working principle: When an elderly person places a tray containing different dishes onto the top surface of the conveyor belt a6, they can choose between self-selection and weighing. When choosing self-selection, the elderly person simply places the selected dishes on the top surface of the conveyor belt a6. At this time, motor a3 rotates the transmission rod a4, causing the conveyor belt a6 to move with the tray. When the tray reaches the bottom edge of the food inspector 111, the inspector counts the types of dishes inside the tray. When the elderly person chooses weighing, the dishes are directly... The tray is placed in the middle of the conveyor belt a6. The hydraulic rod a1 retracts the tightening shell a2, making the conveyor belt a6, which was in a taut state, relax. At this time, the conveyor belt a6 will fall and overlap the top surface of the overlapping support plate 114 under the weight of the tray itself. The weight of the top surface of the overlapping support plate 114 is then weighed by the weighing device 113. The type and weight of the dishes inside the tray are observed by the food inspector 111 and the weight is counted. This achieves the effect of marking the price and weight of the current dishes through the cash register 13. When the dishes are moved for billing, the infrared detector 126 on the outer surface of the fixed support plate 12 performs an infrared scan on the elderly person in front of the integrated cash register 11 to detect and process the height of the elderly person. At this time, the infrared detector 126 controls the motor 121 to rotate the rotating plate 122, and changes the angle of the cash register 13 on the outer surface of the rotating plate 122 toward the elderly person's head position, so that the screen is kept horizontal with the eyes, avoiding the screen's reflected light from directly shining into the eyes, which would cause glare and blur the elderly person's vision. This achieves the effect of making the screen parallel to the elderly person's eyes according to different heights, reducing the blurring of the eyes caused by the reflection of the surrounding image. As the conveyor belt a6 rotates continuously under the motor a3, a small water pump c2 draws water from the oil removal tank c1, causing the water mixed with grease and detergent to directly impact the outer surface of the conveyor belt a6. The grease and detergent washes away the grease on the surface of the conveyor belt a6. As the conveyor belt a6 continues to slide, the scraper bar c4 on the top surface of the oil removal tank c1 scrapes off the grease and detergent and grease from the surface of c6. The inclined surface of the scraper bar c4 allows the grease and detergent to flow into the interior of the oil removal tank c1, thereby recovering the grease and detergent. This achieves the effect of using the grease and detergent to wash away the grease on the surface of c6 and to maintain the cleanliness of the c6 surface.
